Low Supply Current: 2.3mA max  
Low Offset Drift: 10mV/°C max  
Low Input Bias Current: 20pA max  
Very Low 1/f Noise: 250nVPP  
Low Noise: 6.5nV/√Hz  
The OPA141, OPA2141, and OPA4141 amplifier  
family is a series of low-power JFET input amplifiers  
that feature good drift and low input bias current. The  
rail-to-rail output swing and input range that includes  
V– allow designers to take advantage of the  
low-noise characteristics of JFET amplifiers while  
also interfacing to modern, single-supply, precision  
Wide Bandwidth: 10MHz  
analog-to-digital  
converters  
(ADCs)  
and  
Slew Rate: 20V/ms  
digital-to-analog converters (DACs).  
Input Voltage Range Includes V–  
Rail-to-Rail Output  
The OPA141 achieves 10MHz unity-gain bandwidth  
and 20V/ms slew rate while consuming only 1.8mA  
(typ) of quiescent current. It runs on a single 4.5 to  
36V supply or dual ±2.25V to ±18V supplies.  
Single-Supply Operation: 4.5V to 36V  
Dual-Supply Operation: ±2.25V to ±18V  
No Phase Reversal  
All versions are fully specified from –40°C to +125°C  
for use in the most challenging environments. The  
OPA141 (single) and OPA2141 (dual) versions are  
available in both MSOP-8 and SO-8 packages; the  
OPA4141 (quad) is available in the SO-14 and  
TSSOP-14 packages.
